Abstract
We consider the phase structure of the linear quiver gauge theory, using the ’t Hooft anomaly matching condition. This theory is characterized by the length of the quiver diagram. When is even, the symmetry and its anomaly are the same as those of massless quantum chromodynamics. Therefore, one can expect that the spontaneous symmetry breaking similar to the chiral symmetry breaking occurs. On the other hand, when is odd, the anomaly matching condition is satisfied by the massless composite fermions. We also consider the thermal partition function under the twisted boundary conditions. When is even, from the anomaly at finite temperature, we estimate the relation between the critical temperatures associated with the confinement/deconfinement and the breaking of the global symmetry. Finally we discuss the anomaly matching at finite temperature when is odd.
